+rust-gdbgui
+===========
+gdbgui - https://gdbgui.com - is a graphical front-end to GDB
+that runs in a browser. This script invokes gdbgui with the Rust
+pretty printers loaded.
+
+Simple usage : rust-gdbgui target/debug/myprog
+With arguments: rust-gdbgui 'target/debug/myprog arg1 arg2...'
+ (note the quotes)
+
+
+Hints
+=====
+gdbgui won't be able to find the rust 'main' method automatically, so
+in its options make sure to disable the 'Add breakpoint to main after
+loading executable' setting to avoid a 'File not found: main' warning
+on startup.
+
+Instead, type 'main' into gdbgui's file browser and you should get
+auto-completion on the filename. Just pick 'main.rs', add a breakpoint
+by clicking in the line number gutter, and type 'r' or hit the Restart
+icon to start your program running.
